CHAPTER 21
Bandwidth Management
21.1 Overview
This chapter contains information about configuring bandwidth management and editing rules.
ZyXEL’s Bandwidth Management allows you to specify bandwidth management rules based on an
application.
In the figure below, uplink traffic goes from the LAN device (A) to the WAN device (B). Bandwidth
management is applied before sending the packets out to the WAN. Downlink traffic comes back
from the WAN device (B) to the LAN device (A). Bandwidth management is applied before sending
the traffic out to LAN.
Figure 102 Bandwidth Management Example
You can allocate specific amounts of bandwidth capacity (bandwidth budgets) to individual
applications (like VoIP, Web, FTP, and E-mail for example).
